SPECIFICATION forming part of Letters Patent No. 703,769, dated July 1,1902.

Application filed February 26, 1901. fierial No. 48,650. (No model.)

To aZZ whom, it may concern;

Be it known that I, GEORGE ERWI DE LONG, a citizen of the United States,anda resident of the city, county, and State of New York, have inventedcertain new and useful Improvements in Motor-Vehicles, of which thefollowing is a specification. V

My invention relates to motor-vehicles, and more particularly tomotor-cycles.

[0 My invention has for an object to do away with the auxiliarycasingsand attachments ordinarily removably secured to the frames ofmotor-cycles, and thus to greatly reduce the Weight and improve theappearance thereof.

Other objects of my invention are to improve and simplify theconstruction of motor-cycles and render them more practicable and moreconvenient in use.

My invention consists in the novel parts,im-

2o provements, and combinations herein shown and described.

The accompanying drawings, which are referred to herein and form a parthereof, illustrat-e one embodiment of my invention and 2 5 serve,inconnection with the description herein, to explain the principles of myinvention and the best mode in which I have contemplated applying thoseprinciples.

Of the drawings, Figure 1 is aside eleva tion, partly in section, of amotor-cycleconstructed in accordance with my invention. Fig. 2 is asectional view, on an enlarged scale, illustratinga detail of theconstruction. Fig. 3 is a sectional elevation taken on the line 3 3 ofFig. 1.

In carrying out my invention I construct a hollow or tubular frame andform the receptacles for the fuel-supply and other adjunctive devices ofthe motor within the hollow or tubular sections of the frame. Ipreferably use a gasolene-motor of the De Dion type, the explosivemixture for which is supplied by means of a carburetor of the atomizingtype and the igniting devices of which consist-of one 5 or morebattery-cells and a sparking coil. In

the drawings I have illustrated my invention as applied to a bicyclehaving a tubular frame of the ordinary diamond pattern.

Referring now to the drawingsin detail, 1 represents the motor, whichpreferably and as shown is located directly above the main or crankshaft 2 of the bicycle, the upright brace 3 of the frame being to thisend divided at its lower portion into two or more branches or members,between which the motor 1 is secured. As shown, two branches 4 and 5 ofthe upright brace are provided at the rear of the motor and are made toconform to the general Outline thereof. These branches 4 and 5 aresecured at their lower ends to the branches or members 6 and 7 of thelower rear brace of the frame, preferably at or near the point wherethese members are secured together by the usual transverse brace 8,which is arranged just in advance of the rear Wheel of the bicycle. Byreason of this construction the motor and crank-bracket are brought asnear as possible to the rear wheel of the bicycle, and the wheel-base ofthe latter is therefore not unduly extended. A third branch or member 9of the upright brace 3 is arranged in front of the motor and ispreferably secured at its lower end to the lower forward brace 10 of themotor frame. A transverse brace 11 is arranged near the top or head ofthe motor and acts to secure the same in place and to strengthen thebranches 4, 5, and 9 of the upright brace 3.

The power-shaft of the motor is provided with a small pinion 12, whichmeshes with a larger pinion 13 on the crank-shaft 2. The opposite end ofthe shaft 2 is provided with a small sprocket-wheel 14, which connectswith another sprocket-wheel 15 on the rear wheel of the bicycle by meansof a chain 16. The crank-shaft is preferably provided with a suitableclutch, so that it may be held from rotation by the rider when thebicycle is being driven by the motor, as is usual in motor-cycles. Asthe details of this clutch mechanism 0 do not form a feature of mypresent invention, they have not been shown and need not be furtherdescribed.

In the construction shown the upper for ward brace 17 of the frame isconstructed and 5 arranged to form a receptacle for the fuel-supply ofthe motor. To this end the brace 17 is closed at its forward end,where-it is secured to the head 18 of the frame, and the upper end ofthe upright brace 3 and the coupling-piece or bracket 19 are so securedtogether and to the rear end of the brace 17 as to form a liquidtightconnection and to constitute a part of the fuel-supply receptacle, asuitable passage being provided between the braces 3 and 17. A closedsocket-tube 21 is provided in the upper end of the brace 3 to receivethe seat-post 22, as shown. The brace 17 is provided, preferably at itsforward end, with a capped opening 23, whereby the receptacle formed inthe brace maybe supplied with fuel. The carbureter for the motor ispreferably formed in the brace 3 just above the motor. The carburetershown comprises a supplypipe 24, curved at its lower end, so as todischarge the liquid fuel upwardly. A valve 25 is arranged in thesupply-pipe, the controlling-handle of which is arranged outside of thebrace 3 within easy reach of the rider. An opening 26 is arranged abovethe discharge-opening of the fuel-supply pipe 24 to admit the supply ofair. The opening 26 is provided with a suitable regulating-valve 26 tocontrol the supply of air. A perforated plate or screen 27 is arrangedbelow the'fuelsupply pipe and the air-opening, and a passage 28 isarranged below the screen 27 to convey the explosive mixture from thecarburetor to the motor. A relief-cock 29 is arranged at one side of thetop of the motor in position to be easily reached by the rider. Theexhaustpipe 30 of the motor is preferably arranged at the back thereofand between the members 4 and 5 of the upright brace, the lower end ofthe exhaust-pipe terminating in a muffler 31, which is arranged betweenthe members 6 and 7 of the lower rear brace of the frame and just inadvance of the transverse brace 8.

The igniting devices of the motor are pref erably and as shown arrangedin the lower forward brace 10 of the frame. To this end the brace 10 isextended at its lower end beneath and beyond the bracket which carriesthe main shaft 2 of the motor, so that the igniting devices may beinserted therein and removed therefrom. The igniting devices preferablyconsist of a sparking coil and a plurality of battery-cells 36. Asshown, an insulated contact piece 37 is permanently fixed at the upperend of the brace 10 and the sparking coil 35, and each of thebatterycells 36 is provided at each end with a contact-piece, so thatwhen they are put in place in the brace 10' and the lower end of thelatter is closed, as by the screw-cap 38, the electric connections fromthe contact-piece 37 through each of the said elements of the ignitingdevices to the frame of the motor through the cap 38 is made complete.The contactpiece 37 is connected with an insulated wire 39, which passesthrough the head of the frame to a suitable switch 40, located on theframe within easy reach of the rider. The switch 40 may be connectedwith the usual circuit-breaker on the motor (not shown) in any suitablemanner. As shown, an insulated wire 41 passes from the switch 40 downthrough the head of the frame and then through the lower forward brace10 at one it may obviously be located at any convenient point on themachine, as in one of the grips of the handle-bars.

It will be noted that aside from the motor there are no attachmentssecured to the out side of the frame of the bicycle. There are nocasings or receptacles to mar the appearance of themachine or to beloosened by the vibrations thereof While on the road. It will be notedalso that all the extra weights of the casings or carriers usuallyemployed in motor-cycles are dispensed with, the tubular braces of theframe itself being made to take their places. All parts of the apparatusare securely held in place, and the construction in general is simpleand compact and not apt to get out of order.

My invention is not limited to the precise construction shown or to theprecise construction by which it maybe carried into effect, as manychanges may be made therein without departingfrom the principles of myinvention or sacrifice its chief advantages.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is
